Typedef Documentation

typedef int anjay_dm_instance_create_t(anjay_t *anjay, const anjay_dm_object_def_t *const *obj_ptr, anjay_iid_t iid)

A handler that creates an Object Instance.

Param anjay:

Anjay object to operate on.

Param obj_ptr:

Object definition pointer, as passed to anjay_register_object .

Param iid:

Instance ID to create, chosen either by the server or the library. An ID that has been previously checked (using anjay_dm_list_instances_t) to not be PRESENT is guaranteed to be passed.

Return:

This handler should return:

  • 0 on success,

  • a negative value in case of error. If it returns one of ANJAY_ERR_ constants, the response message will have an appropriate CoAP response code. Otherwise, the device will respond with an unspecified (but valid) error code.
